Reconciliations In addition to the results reported in accordance with accounting principles generally accepted in the United States (“GAAP”) included in this report, the company has provided information regarding certain non-GAAP financial measures. See Tenneco’s Fourth Quarter and Full-Year 2011 Financial Results filed on Form 8-K on February 2, 2012 for a reconciliation of EBIT to Adjusted EBIT, Net Income to Adjusted Net Income and earnings per share, Net Income to EBITDA*, EBITDA* to Adjusted EBITDA*, Net Debt/Adjusted EBITDA* and adjusted EBIT as a percentage of value-add revenue. We present debt net of cash balances because management believes it is a useful measure of our credit position and progress toward reducing leverage. The calculation is limited in that we may not always be able to use cash to repay debt on a dollar-per-dollar basis.
